Heat and humidity can make it hard to breath

Arizona summers bring intense heat, and when you're living with COPD, the heat can feel like it's working against you. The good news: with a few simple habits, you can enjoy your summer and keep your breathing steady. Here's what to know.

Why heat is harder on you

When it's hot, your body works overtime trying to cool itself down. That extra effort means your heart and lungs have to work harder too — and with COPD, your lungs already have less reserve to draw on. High heat and poor air quality can trigger shortness of breath, wheezing, or a flare-up faster than they would for someone without lung disease.

Know the two things Arizona throws at you

Heat. Phoenix, Tucson, and much of the state regularly hit 105°F or higher in summer. Even a short walk to the mailbox on a bad day can leave you winded.

Ozone and dust. On hot, sunny days, ozone builds up in the air, usually worst in the afternoon. Dust storms can roll in fast and fill the air with fine particles. Both can irritate your airways.

Before you head out, check the air quality forecast. Maricopa County and the Arizona Department of Environmental Quality post daily air quality alerts online, and many weather apps show an air quality number right next to the temperature. If it says "unhealthy" or there's an ozone action day, it's a good day to stay inside.

Simple habits that make a big difference

Plan around the clock, not just the calendar. Mornings before 9 a.m. and evenings after 7 p.m. are usually the coolest and cleanest air of the day. Save errands, walks, or gardening for those windows.

Take care of your cooling system. If you use a swamp cooler (evaporative cooler), keep in mind it adds humidity, which can make breathing feel harder on very humid days. Change filters regularly, and if you notice it's not keeping up, consider a portable AC unit or fan as backup, especially in the bedroom where you sleep.

Drink water throughout the day, not just when thirsty. Dehydration makes mucus thicker and harder to clear. Keep a water bottle within reach and sip regularly. Go easy on caffeine and alcohol, since both can dehydrate you further.

Dress light. Loose, breathable, light-colored clothing helps your body release heat instead of trapping it.

Protect your medications and equipment. Never leave inhalers, nebulizer solution, or oxygen equipment in a hot car — even for a few minutes, Arizona car interiors can pass 150°F in summer. Heat can break down medication or damage equipment. Keep a cooler bag in the car if you're transporting these items.

Cool your body, not just your room. A damp cloth on the back of your neck, a cool (not cold) shower, or sitting in front of a fan with a spray bottle of water can bring your body temperature down quickly without overexerting yourself.

Know the difference: heat illness vs. a COPD flare

Both can cause shortness of breath, but they need different responses.

Heat exhaustion often comes with heavy sweating, dizziness, nausea, headache, and a fast but weak pulse. Moving to a cool space, drinking water, and resting usually helps.

A COPD flare typically involves more coughing, more mucus, chest tightness, or your rescue inhaler not working as well as it usually does. This needs your COPD action plan, not just cooling down.

If you're ever unsure which one it is, or symptoms don't improve quickly, treat it as urgent and call your doctor or 911.

Check in on yourself

If you use a pulse oximeter, check it if you're feeling off. Know your normal baseline (ask your doctor what's normal for you), and call your provider if your reading drops below what they've told you is safe, or if it doesn't come back up after resting.

It also helps to have a simple check-in system: a neighbor, family member, or friend who calls or stops by during heat waves, especially if you live alone. Extreme heat is one of the times having a second set of eyes on you really matters.

Keep this handy

• Your rescue inhaler, with you at all times, kept out of direct heat
• Your doctor's number and your COPD action plan
• A water bottle
• The air quality forecast for your area, checked each morning

Summer in Arizona takes some extra planning when you have COPD, but it doesn't have to keep you inside all season. A little preparation goes a long way toward feeling good and staying safe.
